Hi there,

I inserted the rule but get the following error although:


Jun 30 12:45:30 lboxx avc:  denied  { write } for  pid=3190 
exe=/usr/sbin/apache2 name=ip.tmp dev=hdc6 ino=96390 
scontext=system_u:system_r:httpd_t 
tcontext=system_u:object_r:httpd_sys_content_t tclass=file
Jun 30 12:45:30 lboxx avc:  denied  { setattr } for  pid=3190 
exe=/usr/sbin/apache2 name=ip.tmp dev=hdc6 ino=96390 
scontext=system_u:system_r:httpd_t 
tcontext=system_u:object_r:httpd_sys_content_t tclass=file

I just need file creation, chmodding, reading and writing on this folder 
and all its subolders.

Thanks,

Pascal Hahn

The following should solve it:
chcon -t httpd_sys_script_rw_t ip.tmp

Same goes for all other files like it, and you want an entry in 
file_contexts/misc/custom.fc to avoid accidentally relabelling it back.

Hi there,

I fixed all my errors and inserted an own role called laufwerka_t. all 
runs fine. also sudo is doing its job nicely until it should execute the 
reboot command. I only get an error from apache called :


Could not set exec context to system_u:system_r:laufwerka_t.


The laufwerka_t also got a filetype called laufwerka_src_t

here is the most important parts of the definitions i made:
domains/program/laufwerka.te:

type laufwerka_t, admin, domain,  auth_chkpwd, privuser, privrole, 
privlog, privowner, mlstrustedreader, mlstrustedwriter, 
mlstrustedobject, privfd;
role sysadm_r types laufwerka_t;


file_contexts/program/laufwerka.fc:

/var/www/[^/]+/lwa(/.*)?        system_u:object_r:laufwerka_src_t

types/files.te:

type laufwerka_src_t, file_type, sysadmfile;

and finally the changes i made to the apache macro:

domain_auto_trans(httpd_t, laufwerka_src_t, laufwerka_t)


Can anyone now tell me how i can use sudo to execute my reboot?

Thanks a lot

Pascal Hahn

apache rule to make it write in directory

[Pascal Hahn]

Hi there,

I got the problem that my apache2 under selinux running on gentoo linux is
not able to write to a certain directory under htdocs which i need to be
writable.

I need a rule to make it write in that directory but didnt find a
possibility to do so by now.

Perhaps someone can help me out here.

Thanks

Pascal Hahn

Please show us the AVC messages from the access that is denied and then it 
should be easy to demonstrate how to customise the policy to do what you 
require.

Try the following:
file_type_auto_trans(httpd_t, httpd_sys_content_t, httpd_sys_script_rw_t, 
file)
